Seattle Sounders FC is an American professional soccer club based in Seattle, Washington. The Sounders compete in the Western Conference of Major League Soccer (MLS). The club was established on November 13, 2007, as an MLS expansion team, making it the 15th team in the league and the third Seattle soccer club to share the name.
The club's majority owner is Adrian Hanauer, and its minority owners are Joe Roth, Paul Allen and Drew Carey. Two-time MLS Cup winner Sigi Schmid is the club's head coach. The Sounders play their home matches at CenturyLink Field. Along with several organized groups, a 53-member marching band called 'Sound Wave' supports the club at each home match. Seattle competes with rival MLS clubs Portland and Vancouver in the Cascadia Cup.
The Sounders played its inaugural match on March 19, 2009, winning 3–0 over the New York Red Bulls. Seattle has set MLS records for average attendance, led the league in season ticket sales, and qualified for the MLS Cup Playoffs in each of its first seven seasons. The Sounders have led MLS attendance since their inaugural season, consistently drawing an average of 50-65% more than the next highest-drawing team in the league, LA Galaxy. The club's announced attendance average was 43,144 in 2012. The team's players have included United States men's national soccer team captain Clint Dempsey, Obafemi Martins, Academy product and current Sunderland player DeAndre Yedlin, striker Fredy Montero, and Osvaldo Alonso.
The Sounders have won the Open Cup three times in a row, in four consecutive Lamar Hunt U.S. Open Cup final appearances. In 2014, Seattle won their fourth U.S. Open Cup title, defeating the Philadelphia Union in overtime, 3–1. For the first time in franchise history, the Sounders won the Supporters' Shield over the LA Galaxy in the 2014 regular season, also completing their double.
